This was the exact model I had in the early 90s ! It was an amazing build and the gumstick battery was light, too. Loved watching this video:
Happy to say my Walkman collection has grown!
I would steer well clear from this model and the WM-EX50, today, 2022, they always have a broken clutch gear that needs replacement and all the capacitors need replacing to get audio end servo back working. There is no room for capacitors that are not the same size (bigger), else you block the mechanism when the PCB is folded back, it's all SMD and requires quite some skill to replace them. (especially without severing soldering pads from the PCB). They are very pretty and take both a AA or a Gumstick, but not worth the effort to me.
Do you have an advice for a less problematic model? Thanks.
I have the WM-AF604 which is a similar model but with the AM/FM Radio. The belt had disintingrated. Using this video, I was able to find out how the belt should be replaced. The service manual did not have the belt path. Just waiting for the replacement belt to arrive from eBay.
SAME!! This video is a godsend!
Same except my motor cable came off :(
do you have the link for the replacement belt I need one too thanks
@@princethewondercat Just search eBay for "WM-AF604 Belt". A number show up.
@@winthropdc1 thanks did already placed an order
Thank you for this - I have one of these Walkmans from new and have ordered a new drivebelt so will give this a go.
Thank you for the great video. It has been a great help to open this beast. The belt on my A602 was completely disintegrated. I will order one and also replace all electrolytics. If I'm lucky, it might work again.
I got my A602 working. I changed all the electrolytics. All of them had leaked on to the board so i had to clean with denatured alcohol. I also had to resolder the tape type switch as it didn't have good connection with the solderpads. It was so corroded by the leaky capacitors.
I bought that model in 1989, it was £100+ and it was pretty good. It just packed up in 1993 :( I own a great WMD6C now so I no longer have to worry about piddly fiddly small WM!
I bought it only 65£ in France at the same time. With leather case and earphones.
KRAZEEIZATION D6C > 2091
Me, too. Bought it in 1990 for $90US. Loved it. I wish I knew what happened to mine.
Hey, thanks so much for this video. I have one the version with the radio and my belt was completely fucked, but your teardown showed me exactly how the belt snaked around.
Kenneth Hardcastle Glad I could help!
Same here I have you model with the radio belt is deteriorated, where did yo get a replacement, I see them on ebay but don't know how old they are? Thanks
пасиба реально классное видео посмотрела всё короче лайк молодец you are awesome thaaanks
It is, probably, the best Waljman I've ever had. (and I've had a few!). Your video was really instructive to know how to open it. I replaced the belt on my one, (which was desintegrated), but, sadly, it isn't work since a long time ago. Maybe I should have repaired it when it happened, but repairs were so expensive at that time! What happens? battery light doesn't turn on. Maybe it is a capacitor, I don't know. I don't remember what happened when stopped working (yes, I was heavily using it).
Is there any battery leakage on the contacts? It could also be cold solder joints, bad caps, or oxidation. I wish I could give you one certain answer but unfortunately given their age there's a million things that could cause the light not to come on/no power.
This video is most excellent. Definitely assisted in the repair of my Walkman. Very interested in your idea of 3D printing belts for tape mechanisms; I have access to a slew of Ultimaker 3s that I could put to work.
Glad to hear it was useful!
The Dolby switch has that extra bit of play because there was a more upscale model called the WM-B603 that had Dolby C
Ahh, that makes sense figuring the way sony splits features amoung their model lines.
Robbin Eikelboom Or SONY WM-EX49C.
I have Sony Walkman same buzzing symthoms, it can be real intresting video how you replace capacitors.
did you get it fixed?
@@protocode_227 no, it just wait own time.
Ex-50 is quite similar, I had some issue to take it apart. Thanks
Belt decintergration on my wmgx51 with radio and recording ,only AA battery .
Thanks for the right belt path and video.
You welcome. I only found a few pics on some random forum thread I dug up so I thought showing the path in a video would be helpful.
I HAD A MODEL SONY WM-190 cassette player..i tried to fix it
"20 internet points for whoever can name what this is here"
One of poor mechanism series Walkman,also use cheap SMD capacitors.small gear break can affected autoreverse mode.
I've learned to absolutely hate smd electrolytics. A bit of a pain to remove and leaves a nasty burning smell when the leaked electrolyte is heated during desoldering.
Hopefully it does allow one side one way play or play one cassette both sides then stop.
@@sjm4306 Darn... I'm actually having the same issue in my AF604. The auto-reverse mechanism is busted, and does exactly what your does at 20:40, where it refuses to turn the "FWD" takeup reel for more than a second. And leaky capacitors mean I just get a constant squeal when playing tapes. What a shame. This Walkman has one of the finer external builds and designs, in my opinion, with the aluminum and steel casing.
got myself a bid on a WM 22 model off eBay. it will be nice to have a proper Sony player.
Edit: lost out on the bid for that WM 22, but I ended up getting two other Sony WM's a Sport model from the mid 80's and a WM from late 90s, early 2000s. Both in working condition and for cheaper with shipping than what the WM 22 ended up selling for in the auction.
this unit was very fragile. When it was on my possession it broken two times, and went to the guarantee, until the guarantee died, afterwards it sleeped on a shelf.
It was absolutely hard to repair it for the teenager I was.
From my experience opening it up I can definitely see why that would be the case.
Fantastic video
Hello and thank you for the nice informative video. Can you tell what is the size/length of the belt. Thank you
Hello dude, did you make a follow up video for this? I just got the same model and seems like it could use a cap replacement... Thanks for answer in advance tho :) great vid
I have a different walkman model, it's in good condition from ebay. All it needed was new belt cause the other one was on it's last leg. Funny thing is i did it without watching a video. But i'm gonna watch this video in case i get my hands on another walkman.
yabang mo
I'd really like to know if new capacitors fixed the sound (and which ones maybe :D)
Good video
antiNSP Thanks
So my WM-A52 player is having an odd issue. It plays tapes at correct speed, but the play button is suddenly sticking making the Stop, Fast Forward and Reverse buttons not want to properly click into place.
The grease in the metal key mechanism has probably dried up, causing the button to stick. Give it a good clean with ipa to remove the old lube and apply some new to the sliding/contact points.
Yo tuve dos y son una chulada!!!
Hey I was wondering if you still had this cassette player, my dad this same model of Walkman when he was in college and I was wondering if yours still worked outside of what was shown in the video and if not what you did to fix it? I was also wondering potential if it worked if I could buy it from you, I was hope to get his fixed for Christmas but will have to tear into it a bit more to see what's broken on his. If you wouldn't be willing to sell yours could you direct me to where/who you got yours from? Anyways thank you for any help you can give!
I just changed the belt and it plays, winds and rewinds. But it says "iiiiiiiiiiii" a bit external and also in the earphones, so no sound. Hmm...
Kind regards.
Sounds like bad caps in the audio circuitry.
@@sjm4306 Thanks, I'll look into that.
Kind regards.
This noise is for the tantalium capacitors... you must all change, i take the same model... good luck!
Hola Sr. Lozano ¿tiene usted un video sobre el reemplazo de capacitors?
Hello Mr Lozano ¿did you make a video about cap replacement?
Hola lo siento no tengo video sobre reemplazos cual seria tu duda? Saludos@@ralffran
@@robertolozano1789 Hola, gracias por responder. Tengo dos dudas: La primero es con respecto al cambio de capacitores, compre un equipo que hace el mismo sonido al subir el volumen (un chirrido) por lo que tal vez sea necesario reemplazo de condensadores. Sin embargo, estos vienen montados en una base negra pequeña y por la parte de atras de la tarjeta no se ven los puntos para desoldarlos ¿hay que remover esa base o como accedió usted a los condensadores?
Otra duda. El cable plano flexible del motor en mi equipo viene parcialmente roto (no todo el cable solo a la extensión de uno de los pines), por lo cual el motor ya no se mueve... ¿Es posible reemplazar ese cable con cables normales de 0.5 mm?
@@ralffran con un Cautín con punta puedes desmoldar los capacitor con unas pinzas los vas removiendo... El motor puede usar cable o alambre delgado son 4 terminales
its the f2095 the one that causes trouble
Hello there! I have a Sony TCM WM-2091 which did not work, after watching your video I decided to open it up and see, the belt had completely gone, turned into chewing gum! I 3D printed a new belt, got the mechanism to work but noticed some parts where loose so it was auto reversing continuously. I have now put them back but I had to remove some of the wheels to do this, on putting them back I now realize that the centre wheel, the black one with the white center needs a "lock washer" , I think it's called this way.
Do you have any idea where I could get one of these, the internal diameter is 0,8 mm.
Hope you can help, I am just this one little peace away from getting my old walkman to work, I think I've spent between 5-8 hours on it already. My 10 year old son is into my old cassettes and also can't wait for me to fix it.
Thanks very much in advance, I hope you can help.
Congrats on getting so far with the repair and that's awesome your son has taken to tapes. Found this on ebay (www.ebay.com/i/400537379577?chn=ps). I keep the little clips from everything I take apart just in case, in fact this saved me in the discman repair video I just did where I lost a clip. Anyway good luck on finishing repair of your walkman!
Hi, thanks for your reply, unfortunately that seller does not send to Spain, however I have found a seller in the UK, will let you know how I get on when I receive them.
the gum stick battery should have fitted you needed to put it a an angle first.
I've found the after market, chinese green batteries are actually a few mm longer than the original sony ones, thus making them fit a little too snugly for my taste into various cd, minidisc, and tape players I've tried putting them in.
@@sjm4306 i've just received a WM-F2095 from ebay this morning that is faulty so found your video very helpful as i think mine is the radio ver of yours, i have the orange VAPEX gumstick batteries for my minidisc and CD players that have fitted perfectly.
My device are similar but is a WM-A602. The problem are in the battery I think... the red led off and don’t play... :(
You can help me?
TheILAIR Check to make sure the battery contacts are clean. If that's not the problem then open it up to inspect the circuit board. If any traces look corroded they need to be repaired or capacitors that are swelling/leaking they need to be replaced.
Thank you! i try it

Do you still have this?
Yes somewhere, I just moved so it's still boxed up with most of my audio player collection.
Where can I buy a belt for it
I got mine from an ebay seller that sold belts for lots of models
I found one in a motorcycle tank bag
I THINK HE SHOULD TEST IT WITH CASSETTE INSIDE, SO THAT HE WOULD KNOW IF THERE IS A PROBLEM..TANGA
Crap model
They always need new capacitors
And the mechanism fails bad
I got one of these with a melted belt, what can i use to replace it?
There's a seller on ebay who still makes replacement belts for a range of these old models.
What kind of screwdriver/size did you use? Please and thanks!
I honestly dont remember the size, but it was one of my smallest phillips (that I use for tiny screws in things like glasses and portable electronics).
It's a Philips Size 000, WIHA PicoFinish 261 P
0.2mm
sorry 2mm
What size belts should I get to replace them on this unit?
This model uses a special very thin and long belt, there's only one seller that I know of on ebay who still has them. Just search the model number and "replacement belt" to find what you need.
@@sjm4306 thanks! Just ordered mine
WM-2091/WM-F2095/WM-190
i'm gonna buy an expensive walkman, but i don't have a cassette to try it with. logic
Andreas Georgiakakis I do have cassettes to test with but it's not like I carry them all with me to college. At the time I made this video I was in my apartment in another state so I had to wait till I visited home. When I got a chance to finally test the tape mechanically plays fine but it seems all the caps in the audio circuit have perished so there is a horrible whine. I'll need to replace them all.
i don't care
Andreas Georgiakakis Says he doesnt care ... yet he replies ... logic
